- The files in udev-rules should be copies to
     /etc/udev/rules.d
  this will ensure stable names in /dev for input devices and
  the ttys that talk to the 3G modem.

- Kernel can be compiled using a cross compiler.  I use
    angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain.tar.bz2
  from  http://www.angstrom-distribution.org/toolchains/

  This goes in /usr/local/angstom.
  I then compile with

   export PATH=$PATH:/usr/local/angstrom/arm/bin
   export CROSS_COMPILE=/usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-
   mkdir O
   make O=O gta04_defconfig
   make O=O -j8 uImage
   rm -r M; mkdir M
   cp O/arch/arm/book/uImage M
   make O=O INSTALL_MOD_STRIP=1 INSTALL_MOD_PATH=`pwd`/M modules_install


  then the uImage and modules are in 'M' ready to be copied


- Directory 'scripts' includes some sample scripts to various
  simple tasks

  + vibra.py shows how to program the vibrator as a rumble effect.
